The usual approach to solve this problem is to assume that each object
will not change its motion behavior abruptly, such as it is done
with Kalman filters [1]} by the use of an appropriate motion
model. The animal tracking problem, however, is not enhanced with such
assumption since the presence of other objects or animals will usually
interfere with the animal behavior. For example, in the test sequence here presented, when an ant encounters
another on its path, it will not continue with the same speed, such
as the usual approaches assume, but will instead stop and most of the times
reverse its direction as a result of the interaction.
